as others have said i do not see any real advantage with ssd drives though. i find even on win 7 and 8 (and 10) if you are still using spinning drives defragging can for sure help. if you download the standalone you can easily opt out of anything and nothing gets installed. imo for free puran defrag is an excellent choice also. now mydefrag *can* do a better job is its configured properly but under normal use of just click and go i do not see this. imo even though its a bit heavier and slower than a few others perfectdisk for me wins. I have done EXTENSIVE tests a while back on pretty much every defrag program out there. all defragger who are logging something are slow this way.įastest defrag were defrag express (same vendor as UltimateDefrag) but outdated and Vopt (also outdated).įrom time to time i check auslogics defrag pro (if the provide some update), if you care about O&O defrag check out their free license for older versions.ĭefragging - ask 3 people and you get 4 answers, same old story.ītw IObit at least is crap ware at all their products - and contains anytime adware.

Raxco perfectdisk was really fast up to version 7 after that time all were crap and much more slower than windows defrag, awful. Mydefrag is upgrade to jkdefrag but both have issues on modern systems (uses also windows api) Software depends on some needs, since they use same api (as mentioned) its all in the GUI. Since hard drives became really fast defragging on ntfs drives is not really neccessary. boot defrag same pointless, windows handling for prefetch cache pretty good. defragging is usefull on a storage device but somehow pointless on a system partition. get a specialist you get a kernel driver but sometimes trouble du that. At least all free defraggers use the windows api and/or VSS thats why they are slow.
